… No answer means no, I guess?
I only responded to your main post here to say that TPL has nothing to do with note recording.
You got no other answers from me yet because I don’t keep a Mac system or MIDI controller at home, and I haven’t been to Renoise HQ yet this week where I do have access to both of those things.
It will be tomorrow at the very least before I’m able to test anything you’ve posted so far. Even then, I’m not really a Mac user in the first place, I don’t have the exact same setup as you, nor the same timing and playing abilities, etc, so my own tests may ultimately reveal nothing special anyway.
Somebody told me that at least the refresh rate meta modulation actually is dependent on TPL… Is this true?
Correct. TPL is also responsible for how often a meta device will “tick” and send its output to the other connected device(s). I briefly mentioned this above, and it’s also mentioned in the manual.
An LFO will pump out its current value 12 times every pattern line (or whatever TPL is set to). Even when the LFO is tuned to its fastest possible frequency of 1 line per cycle, the default 12 ticks per line is still quite enough to represent a basic sine shape for the purposes of modulating some other parameter.
Whatever you connect the meta device to is also likely to be interpolated anyway. For example, pretty much anything in Renoise relating to volume, panning, filter frequency (especially those with intertia), and so on, will apply its own smoothing “in between” ticks depending on what it needs.
In the future, I think it would make sense to finally separate TPL away from the meta devices, so that TPL can really only be applied to the classic sample commands, and then the meta devices have their own more flexible (and higher frequency) modulation rate, similar to how we beefed up the instrument sample modulation rate in 3.0. But that’s a discussion for another time.
